U.S. Coast Guard says a patrol boat and a cutter was deployed to help the Bay State Cruise Company's Provincetown IV before the ferry was able to get its starboard engine running as help was coming. The Provincetown IV came to Boston on its own power with the Coast Guard's cutter by its side in the event there were more problems, officials said.

"The water hit and it was like this huge green sheet of water," said passenger Polly Burnell.

The Bay State Cruise Company says the captain of the ferry was taken away by ambulance after suffering a minor hand injury from a cut. The wave broke two of the seven windshields of the pilot house, where the captain navigates from. Officials say there were no other injuries.

In a statement, the Bay State Cruise Company said, "When the wave broke the windows, the vessel's control systems went off line for a period of time. The captain was able to bring the starboard engine up to speed, but not the port engine."
